1. A breast milk collecting method by stimulating the mammary gland of a breastfeeder to eject breast milk, wherein the breast milk collecting method comprises:
providing an audio-playing device to generate an auditory stimulation, so that the pituitary gland of the breastfeeder is stimulated directly by the auditory stimulation to secret prolatine or oxytocin, thereby allowing the mammary gland of the breastfeeder to eject the breast milk; and
providing a breast pump to generate a tactile stimulation and collect the breast milk, wherein the breast pump is placed on a breast of the breastfeeder and the breast pump comprises:
a main body having an accommodation space;
a breast milk suctioning shield assembled in the accommodation space and detachably connected to the main body, wherein a front end of the breast milk suctioning shield has a breast shielding portion, and a nipple passage extends from a rear end of a center portion of the breast shielding portion;
at least one deformable member is assembled with an annular connection portion located between the breast shielding portion and the nipple passage, and the least one deformable member is controlled by an air pump to be inflated or deflated alternately to touch and press the breast so as to mimic a breastfeeding condition to generate the tactile stimulation, so that the pituitary gland of the breastfeeder is stimulated directly by the tactile stimulation to secret prolatine or oxytocin, thereby allowing the mammary gland of the breastfeeder to eject the breast milk to be collected by the breast pump;
at least one non-deformable supporting member protruded from an inner surface of the annular connection portion and placed at a location corresponding to the at least one deformable member in the annular connection portion;
a breast milk container assembled at a bottom portion of the main body and corresponding to a breast milk outlet of the nipple passage to form an outflow passage;
a first detector disposed at a rear portion of the nipple passage of the breast milk suctioning shield; and
a second detector disposed on a periphery of the outflow passage, the first detector and the second detector detect the presence of the breast milk in the nipple passage and the outflow passage, respectively, so as to determine whether the mammary gland of the breast ejects the breast milk.
